This optical Illusion is the creation of Herman J. Verwaal of Exloo, Netherlands. This is an amazing illusion the two halfs keep trying to pull apart from each other.
Herman has a large collection of optical illusions that he has created over time. He has generously allowed me to feature a few of his pieces here. This is the fourth (here is the first, second and the third) of many. I love the constantly expanding image. His illusions run the gambit and I will be showing you more of his excellent Trick-Art in the future.
